Question

Evaluate the expression

Answer 1

Answer:

  10

Step-by-step explanation:

$\dfrac{5\cdot x^3}{x^2}=5x$

For x=2, this is ...

  5·2 = 10

Answer 2

Answer:

10.

Step-by-step explanation:

We have been given an expression $\frac{5\cdot x^3}{x^2}$. We are asked to evaluate our expression for $x=2$.

To evaluate our expression, we will substitute $x=2$ in our given expression.

$\frac{5\cdot 2^3}{2^2}$

Using exponent rule $\frac{a^m}{a^n}=a^{m-n}$, we will get:

$5\cdot 2^{3-2}$

$5\cdot 2^{1}$

$5\cdot 2$

$10$

Therefore, the value of our given expression is 10.
